01:21 Sgeo: I'm learning Common Lisp, but have looked at Racket before. I think I like Common Lisp's system for keyword arguments, but: Is the whole thing with combining &optional and &key in CL (optional and keyword arguments) a motivation for Racket's keyword system being the way it is, to make it unambiguous when a Racket function has both optional and keyword arguments?

16:48 offby1: actually three lists of length 3 would be plenty fast.
16:48 offby1: cumbersome, though, maybe.
16:48 offby1: there's probably some PLaneT package for multi-dimensional arrays.  There might even be a SRFI.

17:27 haffe: How does garbage collection in racket work? ref count? I have a queue implemented as single linked list. Now I wonder if I have to set the cdr of the deleted element to null when I do a delete.
17:39 offby1: I doubt it's ref-counting.
17:39 offby1: I wouldn't bother setting the thing to nil
17:40 offby1: if an object isn't reachable, it'll get destroyed eventually.
17:40 (quit) Skola: Quit: Lost terminal
17:40 offby1: and if you remove an item from the queue, presumably it becomes unreachable
17:41 offby1: the only things I can think of offhand that don't get gc'd (or, don't get gc'd _fast enough_) are file handles; and with those, you avoid leakage by using the "call-with*" functions.

It certainly seems like a wonderfully different departure from arrays in, say, C. The closest I've come is something called Dope Vectors, but I'm not sure whether they're exactly the same thing.
